EK>JR> JR> How do I instruct a modem at 28,800 NOT to hang up when
EK>JR> JR> a receiver is picked up?
EK>JR>WN> You can't do what you want to do. If the modem loses carrier 
acause
EK>JR>WN> someone picks up a phone somewhere, then it waits for the timeout

EK>JR>This is still the best answer I have gotten.
EK>JR>Thank you
EK>Nope, not the best answer. Try what I did, go to Radio Shack
EK>and purchase a teleprotector cat. No. 43-107, I have one in my hand
EK>just now, 9.95 or so. The teleprotector has a bridge circuit and
EK>silicon controlled rectifier in it that senses line voltage and if
EK>the phone line is below a certain level will not provide a connection
EK>to any phone down stream of the protector. The trick than is to wire
EK>straight to the modem but put the teleprotector on any line that goes
EK>to any phones, works 100 percent. When you pick up a phone you get
EK>ziltch and your data isn't corrupted. I split from my main tap into
EK>the house with one wire straight to the modem and all phones are
EK>behind the teleprotector on the other modular bases. Simple circuit,
EK>I wanted to build instead of buy but by the time you buy the enclosure,
EK>parts, modular plugs and crimping tool... well doesn't make sense.
EK>Best regards.
